Waste heat retrieval system of vehicle
First Claim
1. A waste heat retrieval system of a vehicle, the system comprising:
- an exhaust gas boiler that uses exhaust gas of an engine to heat working fluid;
a superheater that vaporizes the heated working fluid generated from the exhaust gas boiler, and a turbine that uses the vaporized working fluid generated from the superheater to generate torque;
a reservoir disposed in a lower side of the exhaust gas boiler and in which a predetermined space is formed;
a retrieval line that connects the exhaust gas boiler with the reservoir;
a retrieval supply control valve disposed to open or close the retrieval line;
a control portion that controls the retrieval supply control valve to open the retrieval line such that the working fluid of the exhaust gas boiler is returned to the reservoir if a retrieval condition is satisfied;
a supply line extending from the reservoir to the retrieval control valve;
a working fluid supply pump mounted on the supply line to supply the working fluid of the reservoir to the exhaust gas boiler;
wherein the control portion controls the retrieval supply control valve and the working fluid supply pump to supply the working fluid of the reservoir to the exhaust gas boiler if a supply condition is satisfied,a heating line through which coolant of the engine circulates through the reservoir so as to heat the working fluid of the reservoir;
a heating control valve disposed to open or close the heating line; and
an outside air control valve that selectively connects an interior room of the reservoir and an interior room of the superheater with outside air.

Abstract
A waste heat retrieval system of a vehicle may include a reservoir disposed in a lower side of a exhaust gas boiler and in which a predetermined space is formed, a retrieval line that connects the exhaust gas boiler with the reservoir, a retrieval supply control valve disposed to open or close the retrieval line, and a control portion that controls the retrieval supply control valve to open the retrieval line such that working fluid of the exhaust gas boiler is returned to the reservoir if a retrieval condition is satisfied. Accordingly, the working fluid of the exhaust gas boiler in a waste heat retrieval system may be retrieved to the reservoir and therefore the freezing problem of the working fluid can be substantially resolved.
